hgrc.5: reformatted to avoid big chunks of monospaced text

The man page used to have lines longer than 80 characters, even though
all lines in the hgrc.5.txt file were wrapped nicely. The problem
turned out to be that the indented paragraphs started literal blocks
instead of normal paragraphs. The literal blocks were of course not
wrapped when displayed by man.

In short, the asciidoc rules require lists to be formatted like this:

foo::
  Some description of foo.
+
Another paragraph in the description of foo. It *must* start flush
left and the plus is necessary to indicate that this is a list item
continuation.

Lists with nested lists can be formatted correctly using something
called "open blocks". These blocks are used to group the list items
and are marked by a line above and below with two dashes. See the
asciidoc user guide for the gory details...

alias::
 Defines command aliases.
  Aliases allow you to define your own commands in terms of other
  commands (or aliases), optionally including arguments.
+
Alias definitions consist of lines of the form:
+
    <alias> = <command> [<argument]...
+
For example, this definition:
+
    latest = log --limit 5
+
creates a new command `latest` that shows only the five most recent
changesets. You can define subsequent aliases using earlier ones:
+
    stable5 = latest -b stable
+
*Note*: It is possible to create aliases with the same names as
existing commands, which will then override the original definitions.
This is almost always a bad idea!

[[auth]]
auth::
  Authentication credentials for HTTP authentication. Each line has
  the following format:

    <name>.<argument> = <value>

  where <name> is used to group arguments into authentication entries.
  Example:

    foo.prefix = hg.intevation.org/mercurial
    foo.username = foo
    foo.password = bar
    foo.schemes = http https

  Supported arguments:

  prefix;;
    Either "`*`" or a URI prefix with or without the scheme part. The
    authentication entry with the longest matching prefix is used
    (where "`*`" matches everything and counts as a match of length 1).

    authentication entry with. Only used if the prefix doesn't include
    a scheme. Supported schemes are http and https. They will match
    static-http and static-https respectively, as well.
    Default: https.

  If no suitable authentication entry is found, the user is prompted
  for credentials as usual if required by the remote.

[[decode]]
decode/encode::
  Filters for transforming files on checkout/checkin. This would
  typically be used for newline processing or other
  localization/canonicalization of files.

  Filters consist of a filter pattern followed by a filter command.
  Filter patterns are globs by default, rooted at the repository root.
  For example, to match any file ending in "`.txt`" in the root
  directory only, use the pattern "`*.txt`". To match any file ending in
  "`.c`" anywhere in the repository, use the pattern "`**.c`".

  The filter command can start with a specifier, either "pipe:" or
  "tempfile:". If no specifier is given, "pipe:" is used by default.

  A "pipe:" command must accept data on stdin and return the
  transformed data on stdout.

  Pipe example:

    [encode]
    # uncompress gzip files on checkin to improve delta compression
    # note: not necessarily a good idea, just an example
    *.gz = pipe: gunzip

    [decode]
    # recompress gzip files when writing them to the working dir (we
    # can safely omit "pipe:", because it's the default)
    *.gz = gzip

  A "tempfile:" command is a template. The string INFILE is replaced
  with the name of a temporary file that contains the data to be
  filtered by the command. The string OUTFILE is replaced with the
  name of an empty temporary file, where the filtered data must be
  written by the command.

  NOTE: the tempfile mechanism is recommended for Windows systems,
  where the standard shell I/O redirection operators often have
  strange effects and may corrupt the contents of your files.

  The most common usage is for LF <-> CRLF translation on Windows. For
  this, use the "smart" convertors which check for binary files:

    [extensions]
    hgext.win32text =
    [encode]
    ** = cleverencode:
    [decode]
    ** = cleverdecode:

  or if you only want to translate certain files:

    [extensions]
    hgext.win32text =
    [encode]
    **.txt = dumbencode:
    [decode]
    **.txt = dumbdecode:

[[defaults]]
defaults::
  Use the [defaults] section to define command defaults, i.e. the
  default options/arguments to pass to the specified commands.

  The following example makes 'hg log' run in verbose mode, and 'hg
  status' show only the modified files, by default.

    [defaults]
    log = -v
    status = -m

  The actual commands, instead of their aliases, must be used when
  defining command defaults. The command defaults will also be applied
  to the aliases of the commands defined.

[[diff]]
diff::
  Settings used when displaying diffs. They are all boolean and
  defaults to False.

    for recipients. Addresses, headers, and parts not containing
    patches of outgoing messages will be encoded in the first charset
    to which conversion from local encoding (`$HGENCODING`,
    `ui.fallbackencoding`) succeeds. If correct conversion fails, the
    text in question is sent as is. Defaults to empty (explicit) list.

  Order of outgoing email charsets:
 
    us-ascii             always first, regardless of settings
    email.charsets       in order given by user
    ui.fallbackencoding  if not in email.charsets
    $HGENCODING          if not in email.charsets
    utf-8                always last, regardless of settings

  Email example:

    [email]
    from = Joseph User <[e-mail]>
    method = /usr/sbin/sendmail
    # charsets for western europeans
    # us-ascii, utf-8 omitted, as they are tried first and last
    charsets = iso-8859-1, iso-8859-15, windows-1252

[[extensions]]
extensions::
  Mercurial has an extension mechanism for adding new features. To
  enable an extension, create an entry for it in this section.

  If you know that the extension is already in Python's search path,
  you can give the name of the module, followed by "=", with nothing
  after the "=".

  Otherwise, give a name that you choose, followed by "=", followed by
  the path to the ".py" file (including the file name extension) that
  defines the extension.

  To explicitly disable an extension that is enabled in an hgrc of
  broader scope, prepend its path with '!', as in
  'hgext.foo = !/ext/path' or 'hgext.foo = !' when path is not
  supplied.

  Example for `~/.hgrc`:

    [extensions]
    # (the mq extension will get loaded from mercurial's path)
    hgext.mq =
    # (this extension will get loaded from the file specified)
    myfeature = ~/.hgext/myfeature.py

[[format]]
format::

  usestore;;

merge-patterns::
  This section specifies merge tools to associate with particular file
  patterns. Tools matched here will take precedence over the default
  merge tool. Patterns are globs by default, rooted at the repository
  root.

  Example:

    [merge-patterns]
    **.c = kdiff3
    **.jpg = myimgmerge

[[merge-tools]]
merge-tools::
  This section configures external merge tools to use for file-level
  merges.

  Example `~/.hgrc`:

    [merge-tools]
    # Override stock tool location
    kdiff3.executable = ~/bin/kdiff3
    # Specify command line
    kdiff3.args = $base $local $other -o $output
    # Give higher priority
    kdiff3.priority = 1

    # Define new tool
    myHtmlTool.args = -m $local $other $base $output
    myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
    myHtmlTool.priority = 1

  Supported arguments:

  priority;;
    The priority in which to evaluate this tool.
    Default: 0.
  executable;;
    Either just the name of the executable or its pathname.
    Default: the tool name.
  args;;
    The arguments to pass to the tool executable. You can refer to the
    files being merged as well as the output file through these
    variables: `$base`, `$local`, `$other`, `$output`.
    Default: `$local $base $other`
  premerge;;
    Attempt to run internal non-interactive 3-way merge tool before
    launching external tool.
    Default: True
  binary;;
    This tool can merge binary files. Defaults to False, unless tool
    was selected by file pattern match.
  symlink;;
    This tool can merge symlinks. Defaults to False, even if tool was
    selected by file pattern match.
  checkconflicts;;
    Check whether there are conflicts even though the tool reported
    success.
    Default: False
  checkchanged;;
    Check whether outputs were written even though the tool reported
    success.
    Default: False
  fixeol;;
    Attempt to fix up EOL changes caused by the merge tool.
    Default: False
  gui;;
    This tool requires a graphical interface to run. Default: False
  regkey;;
    Windows registry key which describes install location of this
    tool. Mercurial will search for this key first under
    `HKEY_CURRENT_USER` and then under `HKEY_LOCAL_MACHINE`.
    Default: None
  regname;;
    Name of value to read from specified registry key. Defaults to the
    unnamed (default) value.
  regappend;;
    String to append to the value read from the registry, typically
    the executable name of the tool.
    Default: None

[[hooks]]
hooks::
  Commands or Python functions that get automatically executed by
  various actions such as starting or finishing a commit. Multiple
  hooks can be run for the same action by appending a suffix to the
  action. Overriding a site-wide hook can be done by changing its
  value or setting it to an empty string.

  Example `.hg/hgrc`:

    [hooks]
    # do not use the site-wide hook
    incoming =
    incoming.email = /my/email/hook
    incoming.autobuild = /my/build/hook

  Most hooks are run with environment variables set that give useful
  additional information. For each hook below, the environment
  variables it is passed are listed with names of the form "$HG_foo".

  changegroup;;
    Run after a changegroup has been added via push, pull or unbundle.
    ID of the first new changeset is in `$HG_NODE`. URL from which
    changes came is in `$HG_URL`.
  commit;;
    Run after a changeset has been created in the local repository. ID
    of the newly created changeset is in `$HG_NODE`. Parent changeset
    IDs are in `$HG_PARENT1` and `$HG_PARENT2`.
  incoming;;
    Run after a changeset has been pulled, pushed, or unbundled into
    the local repository. The ID of the newly arrived changeset is in
    `$HG_NODE`. URL that was source of changes came is in `$HG_URL`.
  outgoing;;
    Run after sending changes from local repository to another. ID of
    first changeset sent is in `$HG_NODE`. Source of operation is in
    `$HG_SOURCE`; see "preoutgoing" hook for description.
  post-<command>;;
    Run after successful invocations of the associated command. The
    contents of the command line are passed as `$HG_ARGS` and the result
    code in `$HG_RESULT`. Hook failure is ignored.
  pre-<command>;;
    Run before executing the associated command. The contents of the
    command line are passed as `$HG_ARGS`. If the hook returns failure,
    the command doesn't execute and Mercurial returns the failure
    code.
  prechangegroup;;
    Run before a changegroup is added via push, pull or unbundle. Exit
    status 0 allows the changegroup to proceed. Non-zero status will
    cause the push, pull or unbundle to fail. URL from which changes
    will come is in `$HG_URL`.
  precommit;;
    Run before starting a local commit. Exit status 0 allows the
    commit to proceed. Non-zero status will cause the commit to fail.
    Parent changeset IDs are in `$HG_PARENT1` and `$HG_PARENT2`.
  preoutgoing;;
    Run before collecting changes to send from the local repository to
    another. Non-zero status will cause failure. This lets you prevent
    pull over http or ssh. Also prevents against local pull, push
    (outbound) or bundle commands, but not effective, since you can
    just copy files instead then. Source of operation is in
    `$HG_SOURCE`. If "serve", operation is happening on behalf of remote
    ssh or http repository. If "push", "pull" or "bundle", operation
    is happening on behalf of repository on same system.
  pretag;;
    Run before creating a tag. Exit status 0 allows the tag to be
    created. Non-zero status will cause the tag to fail. ID of
    changeset to tag is in `$HG_NODE`. Name of tag is in `$HG_TAG`. Tag is
    local if `$HG_LOCAL=1`, in repo if `$HG_LOCAL=0`.
  pretxnchangegroup;;
    Run after a changegroup has been added via push, pull or unbundle,
    but before the transaction has been committed. Changegroup is
    visible to hook program. This lets you validate incoming changes
    before accepting them. Passed the ID of the first new changeset in
    `$HG_NODE`. Exit status 0 allows the transaction to commit. Non-zero
    status will cause the transaction to be rolled back and the push,
    pull or unbundle will fail. URL that was source of changes is in
    `$HG_URL`.
  pretxncommit;;
    Run after a changeset has been created but the transaction not yet
    committed. Changeset is visible to hook program. This lets you
    validate commit message and changes. Exit status 0 allows the
    commit to proceed. Non-zero status will cause the transaction to
    be rolled back. ID of changeset is in `$HG_NODE`. Parent changeset
    IDs are in `$HG_PARENT1` and `$HG_PARENT2`.
  preupdate;;
    Run before updating the working directory. Exit status 0 allows
    the update to proceed. Non-zero status will prevent the update.
    Changeset ID of first new parent is in `$HG_PARENT1`. If merge, ID
    of second new parent is in `$HG_PARENT2`.
  tag;;
    Run after a tag is created. ID of tagged changeset is in `$HG_NODE`.
    Name of tag is in `$HG_TAG`. Tag is local if `$HG_LOCAL=1`, in repo if
    `$HG_LOCAL=0`.
  update;;
    Run after updating the working directory. Changeset ID of first
    new parent is in `$HG_PARENT1`. If merge, ID of second new parent is
    in `$HG_PARENT2`. If the update succeeded, `$HG_ERROR=0`. If the
    update failed (e.g. because conflicts not resolved), `$HG_ERROR=1`.

  Note: it is generally better to use standard hooks rather than the
  generic pre- and post- command hooks as they are guaranteed to be
  called in the appropriate contexts for influencing transactions.
  Also, hooks like "commit" will be called in all contexts that
  generate a commit (e.g. tag) and not just the commit command.

  Note2: Environment variables with empty values may not be passed to
  hooks on platforms such as Windows. As an example, `$HG_PARENT2` will
  have an empty value under Unix-like platforms for non-merge
  changesets, while it will not be available at all under Windows.

  The syntax for Python hooks is as follows:

    hookname = python:modulename.submodule.callable
    hookname = python:/path/to/python/module.py:callable

  Python hooks are run within the Mercurial process. Each hook is
  called with at least three keyword arguments: a ui object (keyword
  "ui"), a repository object (keyword "repo"), and a "hooktype"
  keyword that tells what kind of hook is used. Arguments listed as
  environment variables above are passed as keyword arguments, with no
  "HG_" prefix, and names in lower case.

  If a Python hook returns a "true" value or raises an exception, this
  is treated as a failure.

[[http_proxy]]
http_proxy::
  Used to access web-based Mercurial repositories through a HTTP
  proxy.

  For security reasons, Mercurial will not use the settings in the
  `.hg/hgrc` file from a repository if it doesn't belong to a trusted
  user or to a trusted group. The main exception is the web interface,
  which automatically uses some safe settings, since it's common to
  serve repositories from different users.

  This section specifies what users and groups are trusted. The
  current user is always trusted. To trust everybody, list a user or a
  group with name "*".

  users;;
    Comma-separated list of trusted users.
  groups;;
    Comma-separated list of trusted groups.

[[ui]]
ui::
  User interface controls.
  archivemeta;;
    Whether to include the .hg_archival.txt file containing metadata
    (hashes for the repository base and for tip) in archives created
    by the hg archive command or downloaded via hgweb.
    Default is true.

  logtemplate;;
    Template string for commands that print changesets.
  merge;;
    The conflict resolution program to use during a manual merge.
    There are some internal tools available:

      internal:local;;
        keep the local version
      internal:other;;
        use the other version
      internal:merge;;
        use the internal non-interactive merge tool
      internal:fail;;
        fail to merge

    For more information on configuring merge tools see the
    merge-tools section.

  patch;;
    command to use to apply patches. Look for 'gpatch' or 'patch' in
    PATH if unset.
  quiet;;

    the username in hgrc is empty, it has to be specified manually or
    in a different hgrc file (e.g. `$HOME/.hgrc`, if the admin set
    "username =" in the system hgrc).
  verbose;;
    Increase the amount of output printed. True or False. Default is False.


[[web]]
web::
  Web interface configuration.
  accesslog;;

8769:a5d0e821ab77

alias::
 Defines command aliases.
  Aliases allow you to define your own commands in terms of other
  commands (or aliases), optionally including arguments.
+
--
Alias definitions consist of lines of the form:

    <alias> = <command> [<argument]...

For example, this definition:

    latest = log --limit 5

creates a new command `latest` that shows only the five most recent
changesets. You can define subsequent aliases using earlier ones:

    stable5 = latest -b stable

*Note*: It is possible to create aliases with the same names as
existing commands, which will then override the original definitions.
This is almost always a bad idea!
--

[[auth]]
auth::
Authentication credentials for HTTP authentication. Each line has
the following format:

    <name>.<argument> = <value>
+
--
where <name> is used to group arguments into authentication entries.
Example:

    foo.prefix = hg.intevation.org/mercurial
    foo.username = foo
    foo.password = bar
    foo.schemes = http https

Supported arguments:

  prefix;;
    Either "`*`" or a URI prefix with or without the scheme part. The
    authentication entry with the longest matching prefix is used
    (where "`*`" matches everything and counts as a match of length 1).

    authentication entry with. Only used if the prefix doesn't include
    a scheme. Supported schemes are http and https. They will match
    static-http and static-https respectively, as well.
    Default: https.

If no suitable authentication entry is found, the user is prompted
for credentials as usual if required by the remote.
--

[[decode]]
decode/encode::
  Filters for transforming files on checkout/checkin. This would
  typically be used for newline processing or other
  localization/canonicalization of files.
+
--
Filters consist of a filter pattern followed by a filter command.
Filter patterns are globs by default, rooted at the repository root.
For example, to match any file ending in "`.txt`" in the root
directory only, use the pattern "`*.txt`". To match any file ending in
"`.c`" anywhere in the repository, use the pattern "`**.c`".

The filter command can start with a specifier, either "pipe:" or
"tempfile:". If no specifier is given, "pipe:" is used by default.

A "pipe:" command must accept data on stdin and return the
transformed data on stdout.

Pipe example:

  [encode]
  # uncompress gzip files on checkin to improve delta compression
  # note: not necessarily a good idea, just an example
  *.gz = pipe: gunzip

  [decode]
  # recompress gzip files when writing them to the working dir (we
  # can safely omit "pipe:", because it's the default)
  *.gz = gzip

A "tempfile:" command is a template. The string INFILE is replaced
with the name of a temporary file that contains the data to be
filtered by the command. The string OUTFILE is replaced with the
name of an empty temporary file, where the filtered data must be
written by the command.

NOTE: the tempfile mechanism is recommended for Windows systems,
where the standard shell I/O redirection operators often have
strange effects and may corrupt the contents of your files.

The most common usage is for LF <-> CRLF translation on Windows. For
this, use the "smart" convertors which check for binary files:

  [extensions]
  hgext.win32text =
  [encode]
  ** = cleverencode:
  [decode]
  ** = cleverdecode:

or if you only want to translate certain files:

  [extensions]
  hgext.win32text =
  [encode]
  **.txt = dumbencode:
  [decode]
  **.txt = dumbdecode:

[[defaults]]
defaults::
  Use the [defaults] section to define command defaults, i.e. the
  default options/arguments to pass to the specified commands.
+
--
The following example makes 'hg log' run in verbose mode, and 'hg
status' show only the modified files, by default.

  [defaults]
  log = -v
  status = -m

The actual commands, instead of their aliases, must be used when
defining command defaults. The command defaults will also be applied
to the aliases of the commands defined.
--

[[diff]]
diff::
  Settings used when displaying diffs. They are all boolean and
  defaults to False.

    for recipients. Addresses, headers, and parts not containing
    patches of outgoing messages will be encoded in the first charset
    to which conversion from local encoding (`$HGENCODING`,
    `ui.fallbackencoding`) succeeds. If correct conversion fails, the
    text in question is sent as is. Defaults to empty (explicit) list.
+
--
Order of outgoing email charsets:

  us-ascii             always first, regardless of settings
  email.charsets       in order given by user
  ui.fallbackencoding  if not in email.charsets
  $HGENCODING          if not in email.charsets
  utf-8                always last, regardless of settings

Email example:

  [email]
  from = Joseph User <[e-mail]>
  method = /usr/sbin/sendmail
  # charsets for western europeans
  # us-ascii, utf-8 omitted, as they are tried first and last
  charsets = iso-8859-1, iso-8859-15, windows-1252
--

[[extensions]]
extensions::
  Mercurial has an extension mechanism for adding new features. To
  enable an extension, create an entry for it in this section.
+
--
If you know that the extension is already in Python's search path,
you can give the name of the module, followed by "=", with nothing
after the "=".

Otherwise, give a name that you choose, followed by "=", followed by
the path to the ".py" file (including the file name extension) that
defines the extension.

To explicitly disable an extension that is enabled in an hgrc of
broader scope, prepend its path with '!', as in
'hgext.foo = !/ext/path' or 'hgext.foo = !' when path is not
supplied.

Example for `~/.hgrc`:

  [extensions]
  # (the mq extension will get loaded from mercurial's path)
  hgext.mq =
  # (this extension will get loaded from the file specified)
  myfeature = ~/.hgext/myfeature.py

  # Define new tool
  myHtmlTool.args = -m $local $other $base $output
  myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
  myHtmlTool.priority = 1

Supported arguments:

priority;;
  The priority in which to evaluate this tool.
  Default: 0.
executable;;
  Either just the name of the executable or its pathname.
  Default: the tool name.
args;;
  The arguments to pass to the tool executable. You can refer to the
  files being merged as well as the output file through these
  variables: `$base`, `$local`, `$other`, `$output`.
  Default: `$local $base $other`
premerge;;
  Attempt to run internal non-interactive 3-way merge tool before
  launching external tool.
  Default: True
binary;;
  This tool can merge binary files. Defaults to False, unless tool
  was selected by file pattern match.

  tool. Mercurial will search for this key first under
  `HKEY_CURRENT_USER` and then under `HKEY_LOCAL_MACHINE`.
  Default: None
regname;;
  Name of value to read from specified registry key. Defaults to the
  unnamed (default) value.
regappend;;
  String to append to the value read from the registry, typically
  the executable name of the tool.
  Default: None

[[hooks]]
hooks::
  Commands or Python functions that get automatically executed by
  various actions such as starting or finishing a commit. Multiple
  hooks can be run for the same action by appending a suffix to the
  action. Overriding a site-wide hook can be done by changing its
  value or setting it to an empty string.
+
--
Example `.hg/hgrc`:

  [hooks]
  # do not use the site-wide hook
  incoming =
  incoming.email = /my/email/hook
  incoming.autobuild = /my/build/hook

Most hooks are run with environment variables set that give useful
additional information. For each hook below, the environment
variables it is passed are listed with names of the form "$HG_foo".

changegroup;;
  Run after a changegroup has been added via push, pull or unbundle.
  ID of the first new changeset is in `$HG_NODE`. URL from which
  changes came is in `$HG_URL`.
commit;;
  Run after a changeset has been created in the local repository. ID
  of the newly created changeset is in `$HG_NODE`. Parent changeset
  IDs are in `$HG_PARENT1` and `$HG_PARENT2`.
incoming;;
  Run after a changeset has been pulled, pushed, or unbundled into
  the local repository. The ID of the newly arrived changeset is in
  `$HG_NODE`. URL that was source of changes came is in `$HG_URL`.
outgoing;;
  Run after sending changes from local repository to another. ID of
  first changeset sent is in `$HG_NODE`. Source of operation is in
  `$HG_SOURCE`; see "preoutgoing" hook for description.
post-<command>;;
  Run after successful invocations of the associated command. The
  contents of the command line are passed as `$HG_ARGS` and the result
  code in `$HG_RESULT`. Hook failure is ignored.
pre-<command>;;
  Run before executing the associated command. The contents of the
  command line are passed as `$HG_ARGS`. If the hook returns failure,
  the command doesn't execute and Mercurial returns the failure
  code.
prechangegroup;;
  Run before a changegroup is added via push, pull or unbundle. Exit
  status 0 allows the changegroup to proceed. Non-zero status will
  cause the push, pull or unbundle to fail. URL from which changes
  will come is in `$HG_URL`.
precommit;;
  Run before starting a local commit. Exit status 0 allows the
  commit to proceed. Non-zero status will cause the commit to fail.
  Parent changeset IDs are in `$HG_PARENT1` and `$HG_PARENT2`.
preoutgoing;;
  Run before collecting changes to send from the local repository to
  another. Non-zero status will cause failure. This lets you prevent
  pull over http or ssh. Also prevents against local pull, push
  (outbound) or bundle commands, but not effective, since you can
  just copy files instead then. Source of operation is in
  `$HG_SOURCE`. If "serve", operation is happening on behalf of remote
  ssh or http repository. If "push", "pull" or "bundle", operation
  is happening on behalf of repository on same system.
pretag;;
  Run before creating a tag. Exit status 0 allows the tag to be
  created. Non-zero status will cause the tag to fail. ID of
  changeset to tag is in `$HG_NODE`. Name of tag is in `$HG_TAG`. Tag is
  local if `$HG_LOCAL=1`, in repo if `$HG_LOCAL=0`.
pretxnchangegroup;;
  Run after a changegroup has been added via push, pull or unbundle,
  but before the transaction has been committed. Changegroup is
  visible to hook program. This lets you validate incoming changes
  before accepting them. Passed the ID of the first new changeset in
  `$HG_NODE`. Exit status 0 allows the transaction to commit. Non-zero
  status will cause the transaction to be rolled back and the push,
  pull or unbundle will fail. URL that was source of changes is in
  `$HG_URL`.
pretxncommit;;
  Run after a changeset has been created but the transaction not yet
  committed. Changeset is visible to hook program. This lets you
  validate commit message and changes. Exit status 0 allows the
  commit to proceed. Non-zero status will cause the transaction to
  be rolled back. ID of changeset is in `$HG_NODE`. Parent changeset
  IDs are in `$HG_PARENT1` and `$HG_PARENT2`.
preupdate;;
  Run before updating the working directory. Exit status 0 allows
  the update to proceed. Non-zero status will prevent the update.
  Changeset ID of first new parent is in `$HG_PARENT1`. If merge, ID
  of second new parent is in `$HG_PARENT2`.
tag;;
  Run after a tag is created. ID of tagged changeset is in `$HG_NODE`.
  Name of tag is in `$HG_TAG`. Tag is local if `$HG_LOCAL=1`, in repo if
  `$HG_LOCAL=0`.
update;;
  Run after updating the working directory. Changeset ID of first
  new parent is in `$HG_PARENT1`. If merge, ID of second new parent is
  in `$HG_PARENT2`. If the update succeeded, `$HG_ERROR=0`. If the
  update failed (e.g. because conflicts not resolved), `$HG_ERROR=1`.

Note: it is generally better to use standard hooks rather than the
generic pre- and post- command hooks as they are guaranteed to be
called in the appropriate contexts for influencing transactions.
Also, hooks like "commit" will be called in all contexts that
generate a commit (e.g. tag) and not just the commit command.

Note2: Environment variables with empty values may not be passed to
hooks on platforms such as Windows. As an example, `$HG_PARENT2` will
have an empty value under Unix-like platforms for non-merge
changesets, while it will not be available at all under Windows.

The syntax for Python hooks is as follows:

  hookname = python:modulename.submodule.callable
  hookname = python:/path/to/python/module.py:callable

Python hooks are run within the Mercurial process. Each hook is
called with at least three keyword arguments: a ui object (keyword
"ui"), a repository object (keyword "repo"), and a "hooktype"
keyword that tells what kind of hook is used. Arguments listed as
environment variables above are passed as keyword arguments, with no
"HG_" prefix, and names in lower case.

If a Python hook returns a "true" value or raises an exception, this
is treated as a failure.

[[http_proxy]]
http_proxy::
  Used to access web-based Mercurial repositories through a HTTP
  proxy.

  For security reasons, Mercurial will not use the settings in the
  `.hg/hgrc` file from a repository if it doesn't belong to a trusted
  user or to a trusted group. The main exception is the web interface,
  which automatically uses some safe settings, since it's common to
  serve repositories from different users.
+
--
This section specifies what users and groups are trusted. The
current user is always trusted. To trust everybody, list a user or a
group with name "*".

users;;
  Comma-separated list of trusted users.
groups;;
  Comma-separated list of trusted groups.
--

[[ui]]
ui::
  User interface controls.
+
--
  archivemeta;;
    Whether to include the .hg_archival.txt file containing metadata
    (hashes for the repository base and for tip) in archives created
    by the hg archive command or downloaded via hgweb.
    Default is true.

  logtemplate;;
    Template string for commands that print changesets.
  merge;;
    The conflict resolution program to use during a manual merge.
    There are some internal tools available:
+
      internal:local;;
        keep the local version
      internal:other;;
        use the other version
      internal:merge;;
        use the internal non-interactive merge tool
      internal:fail;;
        fail to merge
+
For more information on configuring merge tools see the
merge-tools section.

  patch;;
    command to use to apply patches. Look for 'gpatch' or 'patch' in
    PATH if unset.
  quiet;;

    the username in hgrc is empty, it has to be specified manually or
    in a different hgrc file (e.g. `$HOME/.hgrc`, if the admin set
    "username =" in the system hgrc).
  verbose;;
    Increase the amount of output printed. True or False. Default is False.
